The effects of ammonium sulphate, surfactants and spray volume on the activity of glyphosate on Cyperus rotundus: 87

1980

The effect of several wetters and ammonium sulphate on the activity of glyphosate, applied in various spray vols. to Cyperus rotundus, was studied. The addition of ammonium sulphate 5% wt/vol. increased the activity of glyphosate at 0.33-1 kg/ha. Ammonium sulphate activated glyphosate in spray vols. of 26-480 litres/ha. Wetters generally increased the effectiveness of glyphosate, except Agral 1% which was antagonistic.
